Nitrogen (N), Phosphorus (P), da Potassium (K) – muhimman sinadarai guda uku masu gina jiki don tallafawa rayuwar tsirrai masu lafiya. Har zuwa kwanan nan, zaɓin da kawai za a iya yi don auna waɗannan muhimman sinadarai shine a aika samfurin zuwa dakin gwaje-gwaje don yin nazari. Abin takaici, wannan tsari yana da tsada, mai wahala, kuma ba nan take ba. Sakamakon haka, akwai buƙatar kayan aiki masu sauri, a wuri guda waɗanda za su iya isar da sakamako cikin sauri zuwa ga gona.

3. Na'urori Masu auna sigina na lantarki (EC): Binciken "NPK" Mafi Yawa
Kasuwar na'urori masu auna firikwensin 'NPK' masu rahusa da yawa tana ƙara yin ƙarfi, amma wace fasaha ce ke bayan waɗannan ƙananan na'urorin auna firikwensin hannu masu araha? A takaice, wutar lantarki, ko EC.
Na'urori masu auna sigina na EC masu ƙarfin lantarki 2 zuwa 5 suna aiki ta hanyar wucewar wutar lantarki ta waje tsakanin wuraren hulɗa guda biyu (ƙwayoyin ƙarfe) a cikin ƙasa, da kuma auna yadda wannan wutar take tafiya cikin sauƙi zuwa ɗayan gefen. A fannin fasaha, wannan ma'auni ne na yadda ƙasar ke iya sarrafa wutar lantarki, ko kuma ECa, AKA, ikonta na gudanar da wutar lantarki.
Me yasa wutar lantarki ke gudana ta cikin ƙasa? Duk kayan da ke isar da wutar lantarki suna ɗauke da ions, ko ƙwayoyin da ke ɗauke da wutar lantarki. A cikin ƙasa, waɗannan ions suna taruwa a cikin ruwan ƙasa lokacin da gishiri daban-daban suka narke a cikinsa.
Kuma ga babban abin da za a yi la'akari da shi: Na'urar auna zafin jiki ba ta auna kasancewar NPK musamman ba. Tana auna dukkan ions ɗin da ke cikin ruwan ƙasa. Ba za ka iya amfani da fitarwa daga na'urar auna zafin jiki ta asali don yin hasashen takamaiman ions ba. Don haka, waɗannan ba na'urori masu auna zafin jiki na ƙasa na gaske ba ne.
Ƙarfi: Farashi, Sauƙi:

Ana yin na'urorin bincike ne da kayan da suka daɗe, waɗanda ba sa tsatsa, waɗanda suka dace da amfani da su akai-akai a filin.
Iyaka Mai Muhimmanci: Babu Zaɓin Ion:

A cewar bitar fasaha ta wallafe-wallafe, "Ba abin mamaki ba ne, ma'aunin yana da tasiri sosai daga wasu sigogin ƙasa marasa alaƙa, gami da yawan danshi na ƙasa, pH, gishiri, laushi, da kuma sinadaran gabaɗaya." Wani littafin jagorar mai amfani da na'urar firikwensin NPK ya yi iƙirarin cewa yana amfani da "hanyar gano saurin gabaɗaya, don haka akwai wasu kurakurai" kuma ya kamata a yi amfani da shi "da taka tsantsan don amfani da shuka."
Kammalawa: Cinikin da Ya Fi Kwaikwayo Don Amfani Mai Amfani
